Al parecer, la versión de Wii de GH III tendrá "algo más" en la guitarra que las otras..

We are really excited about the Wii game because there are so many options for the Wii remote. However, you will play the game with a guitar peripheral and it will be similar to a guitar you've seen in the past.
Además, se confirma el tema on-line y las descargas de canciones en Wii.

Superb.
